Product Description
The PE43502 is a HaRP™-enhanced, high linearity, 5-bit RF
Digital Step Attenuator (DSA). This highly versatile DSA
covers a 15.5 dB attenuation range in 0.5 dB steps. The
Peregrine 50Ω RF DSA provides multiple CMOS control
interfaces. It maintains high attenuation accuracy over
frequency and temperature and exhibits very low insertion loss
and low power consumption. Performance does not change
with VDD due to on-board regulator. This next generation
Peregrine DSA is available in a 4x4 mm 24-lead QFN footprint.
The PE43502 is manufactured on Peregrine’s UltraCMOS™
process, a patented variation of silicon-on-insulator (SOI)
technology on a sapphire substrate, offering the performance
of GaAs with the economy and integration of conventional
CMOS.

Attenuation Word
Bits must be set to logic low
Attenuation Word is derived directly from the attenuation value. For example, to program the 12.5 dB state:
Attenuation Word: Multiply by 4 and convert to binary → 4 * 12.5 dB → 50 → 00110010
Serial Input: 00110010
